Pitching moment coefficient (Cm) Calculator

The pitching moment coefficient () is a dimensionless coefficient used in aerodynamics to describe the pitching moment experienced by an airfoil. Positive values of indicate a nose-up pitching moment, while negative values indicate a nose-down pitching moment. The formula to calculate Pitching moment coefficient as follows:

Where:

  • is the pitching moment acting on the body (N·m),
  • is the density of the fluid ( kg/m³),
  • is the velocity of the fluid relative to the body (m/s),
  • is the reference area (m²),
  • is the reference length (m).
  • Cm is Pitching moment Coefficient in N-m/m2
